SPECIFICATION forming part of Letters Patent No. 639,639, dated December 19, 1899.

Application filed June 7,1897. Serial No. 639,701. (No model.)

To ctZZ whom it may concern.-

Be it known that we, WALTER H. WILKIN- SON and HORACE L. GEE,citizens of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented new and useful Improvements in Double Trucks, of which the followingisa specification.

The objects of our improvements are to I0 provide a swivel-bolster of a double truck with elements which give it great strength, to provide two-way bolsterguiding pedestals which are secured to the side frames of the truck by means which strengthen the union of the bar members of the side frames and thereby stiffen the latter, to provide with the side frames guiding-pedestals having open upper ends which receive in one line of direction from above the outer ends of the bolster and in a transverse line of direction the elastic end support of the same, to provide with bolster guiding pedestals devices by which the elastic supports of the bolster may be held at a preferred tension while least loaded and be prevented from imparting to the bolster and the car seated thereon a rebound beyond a predetermined limit, and to provide mechanisms by which the weight on the bolster may be transferred through elastic supports to the side frames of the truck at points thereon near the axle-bearings.

Other objects and advantages of the invention will be fully understood from the following description and claiins,when taken in connectionwith the annexed drawings,in which- Figure 1 is a plan of our improved truck. Fig. 2 isa side elevation with parts insection. Fig. 3 is an end view. Fig. 4 is a sectional View taken atline 2 in Fig. 2. Fig.5 is a View of a brake-shoe and adjuncts'thereto with parts in section. Fig. 6 is a section view at line 2 in Fig. 5. Fig. 7 is a section atline 3 in Fig. 2. Fig. 8 is a section through the bolster, taken at line 4 in Fig. 4. Fig. 9 is an with parts in section and illustrating our preferred form of its construction. Fig. 10 is a plan of this preferred bolster. Fig. 11 is a section taken at line 5 in Fig. 9. Fig. 12 is a side elevation of the bolster-spring-housing block detached from the end of the bolster.

Fig. 13 is a sectional view of the bolster, taken at line 6 in Fig. 9. Fig. 14 isaside elevation, part in section, of the middle portion of a side frame with two-way bolster-guiding pedestal, bolster therein,and elastic support between the latter and said truck-frame. Fig. 15 is taken at line 7, Fig. 14. Fig. 16 is a side elevation illustrating an elastic support of modified form imposed between the truckframe and bolster.

Similar letters of reference refer to similar parts throughout the several views.

In the drawings,A A are the wheels of the truck, B B the axles,and O O the journal-bearing housings, and with these above-named parts we prefer to employ side frames D D, comprising each the parallel-bar frames D D and housing-pedestals D D and secured together by suitable end bars E E by means of coupling-pieces and rivets,so as to produce a rigid truck-frame. Our preferred truck-frame, comprising at each side the said two parallelbar frames and pedestals,is of the kind known to the trade as double-diamond trucle frame and composed of the upper bar members a,lower middle bar members a',and lower end bracing members 6&2 (t and the axlehousing pedestals D D arranged between the respective parallelpairs of said bar members a, a, and a at equal distances from the middle of the truck-frame by rivets,which are hot driven and headed. Although these double-diamond side frames may have their bar members to cross each other, yet we prefer to arrange and form them in their middle portions of bars a and a,'as shown in Figs. 2, l4, and 15, in which said middle portions are run horizontal and parallel and set edge to edge, so as to unitedly produce a depth of frame equal to two widths of the said bar members, with each reinforcing and stiffen ing the other.

F F are two-way bolster-guiding pedestals, one at each side of the truck-frame and mounted each on the upper side of the same at points midway between the pedestals D D and having a secure connection. with the parallel bar-frames D D. Although these bolster-guiding pedestals may in some of their portions be differently formed, so as to adapt them for connection and use with truckframes of other modifications of form, yet our preferred form of construction of said ped estals F is shown in Figs. 1 and 2 and in enlarged scale in Figs. 14,15, and 16. These figures show the two-way bolster-guidin g pedestal F to comprise the four upwardly-projected bolster-guiding elements 0 c c 0' set in pairs, one pair cc outside and the other pair 0 0 inside and set at a distance from the outside pair a little greater than the width of the spring or elastic support S, Figs. 1 and 15, which is received between them, while .the guiding elements in each pair a c and c 0' face each other and are set apart to a distance adapted to nicely receive the outer ends of the bolster and the end adjuncts thereof,as shown in Figs. 1, 2, 14, and 16. These guiding elements 0 0 have integral with them the downwardly-projeeted side webs d d, which are set apart, outside measure, to a distance equal to the distance, the parallel bar members a a and a a are set apart, so as to be nicely received between them, as shownin Figs. 4cand 15, and these webs dd are integral with the tyingsleeves c e, which connect said webs and have their perforations 6 continued through said webs, so as to nicely receive the rivets or bolts which may be employed for rigidly securing the bolster-guiding pedestal with the bar members a and a, as shown. For relieving the rivets e from shearing strain these pedestals have integral with their outer and inner websd d the outwardly-projected horizontal flanges f f, one below and the other above, and between which the bar members a a of the side frame are nicely received, so as to be reinforced in their union by the bearing of the respective flanges ffon the respective edges of said bar members, as in Figs. 4., 7, 14, 15, and 16. The upper end of this twoway bolster-guiding pedestal is made open from above, so that an outer end of the bolster and the elastic supporting device connected therewith may at will be introduced from above to between the respective coacting pairs of guiding elements a c c c in said pedestal, as illustrated in Fig. 1, in connection with Figs. 2, 4, 14, 1.5, and 16. The upper end of each guiding element in the respective pairs 0 c is provided with perforation adapted to receive a suitable springkeeper, which may consist of a single piece made in the form of a pin or key, yet we at present prefer this keeper to consist of two parts and comprising the sleeve 0 and bolt 0 Figs. 14, 15, and 16, which will be hereinafter more fully referred to.

G is a bolster mounted on elastic supports H H and arranged with its end portions in the two-way bolster-guiding pedestals F F. This bolster is at the middle of the truck and is arranged transversely to the side frames of the same, with its king-bolt hole 9 relatively midway between said side frames. The elastic supports 11 may be of any suitable form of construction and parts and are arranged relatively transverse to the bolster and secured to the respective ends of the same by bolts, clips, or their known equivalents, so that while each outer end portion of the bolster is arranged between two pairs of the guiding elements 0 c of the two-way bolsterguiding pedestals F the elastic supports, being in the transverse, will be below-and arranged between the pairs of guiding elements 0 c and c c, as shown in Fig. 1. By this arrangement the bolster will hold by its sides with the said pedestals for moving the truck when a draft is applied to said bolster, or said pedestals will hold with the bolsters when the draft is from the truck and communicated to the bolster, while at the same time the elastic supports H will be held by the said pedestals for preventing the bolster having an endwise movement in relation to the truck.

Although the holster G employed in connection with the above-described two-way bolster-guidingpedestals F and the elastic supports H may be made with any preferred suitable construction and consist of one or more pieces, yet we at present prefer the bolster be made with a truss-form construction, of which two forms are shown, one in Figs. 3, 4,- and S and the other in Figs. 9 and 10.

In Figs. 3, 4, and 8 the truss-form bolster is shown to be comprised of the channel-iron top-bar member G, the truss flat-bar member G queen-posts G G and king-bolt post G The truss flat-bar member G is shown to be secured by its outer end portions to the outer end portions of the channel-bar member G by rivets g, while the said queen-posts are shown to be in the form of vertical sleeves, one at each side of the king-bolt post G secured from moving by the binding-bolts g g binding the bar members G (l and said queen-posts rigidly together. At each end of this bolster is secured from the lower side of its channel bar member G spring-block g, Fig. i, which block also serves as a wear or guide block between the guiding elements 0 c of the pedestal F.

Secured by suitable bolts to the bolster at the middle of its length is the usual cup-form coupling-plate I, having its central perforation '5 coincident with the vertical perforation in the king-bolt post G and also secured to this bolster at points near their outer ends are the wearing-plates J, which may be of any suitable form of construction, yet we prefer to use wear-plates of the kind known as cushion or elastic wear-plates.

In Figs. 9 and 10, taken in connection with Figs. 11, 12, and 13, we show our preferred form of trussed bolster. In this preferred form of construction of the bolster Gthe said Figs. 9, 10, 11, 12, and 13 (all taken in connection) show it to be comprised of the channel-iron top member G',the two parallel trussbar members G G the central block J, comprising the queen-posts G3 G and king-bolt post G similar to those shown in trussrform bolster first above described, but made integral with the horizontal upper web j and vertical lower web j and bearing-flanges 7' all of which comprises our preferred members in said central truss-block J, and with said members G G G and central truss-block J are shown to be employed the spring-blockmembers K, one at each end of the said bolster, Figs. 9 and 10. struction of these spring-block members is shown in plan by dotted lines in Fig. 10, by side elevation in Figs. 9 and 12, in its rear end view in Fig. 13, and in its front end View in Fig. 14. These spring block members shown in the said several figures comprise each a single piece of metal and include in the piece the spring-seating-block member 7t, front and rear guiding members It" k horizontal web members extended from the upper portion of the rear guiding member 7& and the vertical Web member 76, extended down from the horizontal web 70 and rearward from said rear guiding member 70 all integral and preferably made of cast-steel or other tough metal. lhese spring-block members are applied to the outer endportions of the channel bar member of said bolster ..and against the lower side of the horizontal web portion of the said channel-bar member G and are secured thereto by rivets Z-Z, Figs. 9, 10, and 13, while the outer ends of the parallel truss-bar members G G are rigidly secured to the web member 70 by rivets Z, which rivets Z, togetherwith rivets l through horizontal Web member and spring-block member, are driven and headed while red-hot. 4 The central block member J of this preferred truss-bolster is arranged between the channel-bar member G and two parallel truss-bar members G G with its upper horizontal webj seated in the channel of member G and has bearing against the horizontal web portion of the same, with its edges against the inner sides of the vertical web portions of said member G, as shown in Fig. 11, while the bearing-flanges 3' Figs. 9 and 11, bear on the upper edges of said parallel-bar members G G, and the vertical lower web j is held between said two members G G and rigidly secured therewith by rivetsj driven and headed while hot. Binding-bolts J passing through the horizontal web of the channel-bar member G and the queen-posts G G in said block J, are shown to hold said parts rigidly secured together and also holding the'coupling-plate I, secured central in the said bolster.

The elastic support Hforbolster G may be, as above stated, of any suitable form of construction which will adapt it to serve to support said bolster from the truck-frame in an elastic manner and be held between the guidin g elements of the bolster-guiding pedestals, and they may each be made to comprise the stiff horizontal bar h, Fig. 16, and spiral springs h h, having spring-seats 72, between and having also spring-seats it below, secured or connected with suitable members of each side frame of the truck and provided The preferred form of conpractice for the construction of this class of spring. The outer ends of this half-elliptic form of elastic support H have their end bearing-seats, as h, made secure to suitable members of the truck-frame at points near the housings of the axle-journals, yet we prefer to form said bearing-seats h integral with the side flanges of the housing-pedestal members D of the truck-frame, as shown in Figs. 1, 2, and 14, so that the load carried by the bolster may be distributed on the truck-frame at points which will be relatively and uniformly near the journals of the axles of the truck-wheels, as shown in Figs. 1 and 2.

Although wear-plates, as J in Figs. 1 and 2, are omitted from the trussed'bolster in Figs. 9 and 10, yet it is to be understood that they are to be employed therewith for steady- 1 ing the car body which may be mounted thereon. V

The bolster G and the elastic supports H being secured together and placed in position in the two-way bolster-guiding pedestals F, as above described, while under the normal condition of the springelements embodied in said elastic supports, resting on their bearings connected with the side frames of the truck and while not under a load or pressure from any source whatever, will be held up as to dotted lines so and z in Figs. 1, 14, and 16, which lines are above the plane said bolster and its elastic supports may stand at when bearing their minimum load, which is illustrated by the full lines said bolster and spring supports are shown at in said figures.

In our practice for assembling the abovedescribed parts and devices ready for use we compress the elastic supports H by a force about equal to that corresponding with the minimum weight or load said elastic supports may bear when ready for active service and for receiving additional weights, as usually attend such service. Although such compression may be effected and kept constant on said elastic supports by any suitable devices, yet we prefer to employ spring-keepers which comprise each a sleeve 0 and bolt 0 Figs. 14, 15, and 16, with the sleeves arranged between the guiding elements 0 c and the bolt passing through perforations c in said guiding elements and said sleeve when the latter is in place and at the upper side of the elastic support or a block, as 0 Figs. 14 and 16. A screw-threaded nut on the said bolt keeps the bolt in place and causes it to serve as a tying device for holding the guiding elements 0 c from spreading in either direction when lateral strains from swaying of the car-body (not shown) are exerted through the bolster and said elastic supports on said two-way bolster-guiding pedestals F.
